Phobias are generally broken down into 3 categories. First, specific or simple phobias are the most common and are triggered by specific objects like spiders. Second, there are Agoraphobia phobias, which center the fear around being in a situation with no easy escape without embarrassment, like having a panic attack when you’re stuck in an airplane (been there, no shame) . The third type is Social phobia which can cause extreme anxiety in public or social situations and can lead to low self-esteem. This third type can cause many social issues such as dropping out of school and being unable to make friends. Are you ready to see what some people are strangely petrified of?
